I’m not as avid a concert-goer as I’d wish, and unfortunately I think some of that is due to general unawareness of the who/where/when of shows. Of course the source of your concert info varies by city, but even here in New York it’s difficult to find one comprehensive and user-friendly list. Bowerypresents.com is usually the safest bet for my taste of music, but you still miss out on great venues – Highline Ballroom, Santos Party House, Central Park, even Jones Beach… The only place for which I’ve found listings for EVERY concert in the area is http://www.pollstar.com.
However, because Pollstar is really just an industry publication, it isn’t that user friendly. Some shows have links for tickets; some don’t. If you really want to find more information about a certain venue or band, don’t bother clicking on the link – you’ll have to Google it yourself.
Perhaps the sheer size, power, and resources of an industry staple like Pollstar is impossible to compete with on a global scale, but it sure would be useful to have a site that covers the major metro areas and is built for the concert enthusiast, not an industry insider.
